Title: Bad vibrations that come and go
Post by: dersteirer on Sep 06, 2021, 03:27:46 pm
Hello,

some weeks ago I got myself a Raider from 2008, used with about 5500 miles on it. An importet bike from the US, as the Raider aren't available here in Germany.

I have a very strange problem: there are strong vibrations all over the bike. When I bought the bike I picked it up and on the way home (about 3hrs) I thought, well, not quite smooth this engine.
A few days after the engine was very normal and smooth. I had a ride and I thought, well, probably the gas was old, or the engine didnít like the gas from Shell or whatever.

Then, a while later, the vibrations got stronger again, bit by bit. And because of a strange engine sound which gave me headaches, I went to the dealer again. On the way there I thought I was going insane due to the vibrations. BTW, I had a power commander installed for a short time, I had the problems with as well as without the PC.

When I arrived at the dealer (3 very annoying hours on the bike), the mechanic had a test ride. The knocking sound (the reason for the visit) was almost not to hear due to the fresh oil change (20w50), I am such an idiotÖ anyways, after a ride the mechanic said ďeverything is normal!Ē. WTF?!? I had a short ride, and nothing, absolutely nothing was wrong!

So we went back home (my wife, in a car, because I wanted to leave the bike there), riding on a German autobahn, everything was ok. I stopped for some gas (Esso) and went homeward bound.
And it started again, [email protected]@iní hell, what is going on? These are hard vibrations, my bum and fingers were numb when I arrived home.

Currently the bike is at a shop for the tuning of the power commander, they are probably the best guys in northern Germany when it comes to bike and car tuning. I told them they should try to find out what is going on, but I donít think they find the reason.

When sheís running normally, there are a bit of vibrations, nothing bad or annoying, quite ok for a single pin layout. And especially at higher RPM sheís pulling like crazy, a weapon!! When there are these vibrations, itís all over the bike.
Has one of you ever had something similar?

Many thanks,
florian

Have you checked the tyres, wheel and true balance? The Raider is a big V Twin  and does have some vibs but what you are describing is not normal

Wheels/tyres are new or almost new. The point is, that it is there, the next time everything is normal for a while.

Does it happen at certain speeds in a certain gear? How old is the battery?

The dealer said the battery is new, when I first visited the bike the battery died.
I am not sure if it occurs in certain rpm, probably in some not that strong, but basically it's there or it's not there.

Did you check the ignition coils for clean/tight connectors? You could be facing a intermittent poor connection issue. Or maybe even an occasionally bad coil.

Is just only vibrating or you can here also a knock sound ?

Thank you for your replies. There is no specific sound or knocking, engine sounds always the same.
I will have a look at the ignition coils, but I don't know how to check the coils. Is there an "easy" way to check them? I think I saw a little bit of corrosion on them.

The one time when I was heading back home from the dealer was the strangest event. On the autobahn a pretty smooth ride, stopped at the Esso gas station for some normal/usual gasoline. And when I started the engine I thought, hmm, does it start again?  it was back again, and very annoying.

I'd also check to make sure the plug wires are secure - also add some Sea-foam to the tank in case you got some bad gas or moisture in the tank.

I could see plug wires being an issue if it were only partially secured on. I had one I didn't get seated well and it came lose and vibrated pretty bad. It could also be that you have a partial break in one of the wires that is only cutting out intermittently. Though I would think the dealer would've definitely checked this if they're any good.

Ok meant to ask this earlier the vibration happens when you are riding - if you pull over and stop does it continue to vibrate while the engine is running?

It vibrates when I let the motor idle. I will check the spark plugs and wires when she's back from the shop. I 'll try to check the coils as well https://www.roadstarraider.com/index.php?topic=136884.0
Thank you for your help. I guess this will take a while until the problem is solved.

The shop should check all of that while the bike is there  :thinking: :shrug:

I would think so.  If not, get a new shop.

Right, I was thinking that too, the shop where I bought it. But when I was there all of a sudden I had no problems and they said as long there is no problem there is nothing that they can do. Not the reaction I wanted... maybe the guys in the tuning shop find out the reason. They have a good reputation, but what counts in the end is, if they find the problem.

This time I didn't want to buy from a private person, so I am on the safe side. Yeah, whatever... :(

During the winter season I will check some things, like valve clearence, syncing the injection and so on. I did a lot of maintenance on my olde Honda Shadow, I spend many many hours, like tuning the air intake and rejetting. Especially the rejetting and syncing took a while, but the result is worht it. The previous owner obviously did not care about maintenance, and she's from 1994.

But the difference to the Yamaha is the price tag, a bike with 6000 miles on it should be in kind of mint condition.

This is exactly why I bought all of my Raiders new.  I realize that's no longer an option with the Raider. Hoping I will not be in the market to get another one.

This would solve all your problems. https://www.facebook.com/groups/YamahaRaider113/permalink/10159519058778162/

and you have north of 170HP when its done. (and thats without turbo)

So I called the tuning shop about the current status of my xv Raider S (I pick her up later in the afternoon):
- he didn't find anything wrong which may have caused the vibrations. WTF...
- he is about finished with the tuning of the Dynojet PC. The mechanic said she was extremely lean at lower rpm, and very very rich at higher RPM.

Now she has about 90 hp on the rear wheel, and about 150 nm torque, which is about 110 ft-lb.
I've read the discussion where folks show their DJ-diagrams/printouts, some have more than 110 hp or 120 ft-lb, I don't think that I will reach these figures. What do you think?

I think itís absolutely worth the work, either I run her in perfect condition or not at all. Thatís more important to me than the HP on the paper.
I have added a tuning air filter made by ďDNAĒ and I have lifted the lid a bit as well. She has the regular US-exhaust, as it is an imported Raider. These Raiders arenít available in Germany, only the Cruiser-XV1900 you can get here.

I tried out such a Cruiser-XV the other day, compared to my Raider quite a poor performance, kinda lameÖ And a very quiet exhaust, sounds like a mofa/mopped/scooter. German exhaust-regulations & laws are pretty strict. So thatís why I am happy with this US-Raider, the noise-values are officially in the papers, so this exhaust -which is louder- is absolutely street legal. And with the new air filter, the tone getís better, too.

And I wonít get into trouble with the cops. And there are almost no aftermarket pipes, there are a few and they are very expensive (1500-2400 Euro for a complete set). I could get some pipes in the US, but sooner or later I get into trouble with them.

I donít know what to do about these vibrations which come and go, maybe I find out during winter. I love that bike, I like the looks, the engine is just cool, the frame is made of aluminum, and despite the weight she handles well.

 They are great bikes! I hope you get the vibration figured out, These are mine
